It basically stops the spasmy crampy stuff, Luce. I get hideous pains, I assume they're maybe colon spasms as several people have mentioned them, that are agony. Sometimes I can't work out if it's period related or I am about to have a massive... accident.

:shame: The Buscopan or the travel sickness things really help with that for me, it's by far the worst bit, I find. My aunt told me about the travel sickness pills as she's always had problems and from my research they seem to just be similar to Buscopan which is basically for cramps and spasms related to IBS and stuff.
A Dr once told me that because everything is so cramped together down there and there isn't much space that all your reproductive bits and your bowel and stomach can get a bit confused and it all goes spasmy mental at the same time, so I figure using something meant for a similar issue won't do any harm.
